- A query specially crafted to exploit a defect in EDNS option processing could cause named to terminate with an assertion failure, due to a missing isc_buffer_availablelength() check when formatting packet contents for logging. For more information, see the security advisory at https://kb.isc.org/article/AA-01166/. [CVE-2014-3859] [RT #36078]
- A programming error in the prefetch feature could cause named to crash with a "REQUIRE" assertion failure in name.c. For more information, see the security advisory at https://kb.isc.org/article/AA-01161/. [CVE-2014-3214] [RT #35899]
- Support for CAA record types, as described in RFC 6844 "DNS Certification Authority Authorization (CAA) Resource Record", was added. [RT#36625] [RT #36737]
- Disallow "request-ixfr" from being specified in zone statements where it is not valid (it is only valid for slave and redirect zones) [RT #36608]
- Support for CDS and CDNSKEY resource record types was added. For details see the proposed Informational Internet-Draft "Automating DNSSEC Delegation Trust Maintenance" at http://tools.ietf.org/html/draft-ietf-dnsop-delegation-trust-maintainance-14. [RT #36333]
- Added version printing options to various BIND utilities. [RT #26057] [RT #10686]
- Optionally allows libseccomp-based (secure computing mode) system-call filtering on Linux. This sandboxing mechanism may be used to isolate "named" from various system resources. Use "configure --enable-seccomp" at build time to enable it. Thank you to Loganaden Velvindron of AFRINIC for the contribution. [RT #35347]
- Adds RPZ SOA to the additional section of responses to clearly indicate the use of RPZ in a manner that is intended to avoid causing issues for downstream resolvers and forwarders [RT #36507]
- rndc now gives distinct error messages when an unqualified zone name matches multiple views vs. matching no views [RT #36691]
- Improves the accuracy of dig's reported round trip times. [RT #36611]
- When an SPF record exists in a zone but no equivalent TXT record does, a warning will be issued. The warning for the reverse condition is no longer issued. See the check-spf option in the documentation for details. [RT #36210]
- Aging of smoothed round-trip time measurements is now limited to no more than once per second, to improve accuracy in selecting the best name server. [RT #32909]
- DNSSEC keys that have been marked active but have no publication date are no longer presumed to be publishable. [RT #35063]
- Updates the URI record type to current draft standard, draft-faltstrom-uri-08, and allows the value field to be zero length [RT #36642] [RT #36737]
- On some platforms, overhead from DSCP tagging caused a performance regression between BIND 9.9 and BIND 9.10. [RT #36534]
- RRSIG sets that were not loaded in a single transaction at start up were not being correctly added to re-signing heaps. [RT #36302]
- Setting '-t aaaa' in .digrc had unintended side-effects. [RT #36452]
- Fixed a bug where some updated policy zone contents could be ignored due to stale RPZ summary information [RT #35885]
- A race condition could cause a crash in isc_event_free during shutdown. [RT #36720]
- Addresses some problems with unrecoverable lookup failures. [RT #36330]
- Addresses a race condition issue in dispatch. [RT #36731]
- acl elements could be miscounted, causing a crash while loading a config [RT #36675]
- Corrects a deadlock between view.c and adb.c. [RT #36341]
- liblwres wasn't properly handling link-local addresses in nameserver clauses in resolv.conf. [RT #36039]
- Disable the GCC 4.9 "delete null pointer check" optimizer option, and refactor dns_rdataslab_fromrdataset() to separate out the handling of an rdataset with no records. This fixes problems when using GNU GCC 4.9.0 where its compiler code optimizations may cause crashes in BIND. For more information, see the operational advisory at https://kb.isc.org/article/AA-01167/. [RT #35968]
- Fixed a bug that could cause repeated resigning of records in dynamically signed zones. [RT #35273]
- Fixed a bug that could cause an assertion failure after forwarding was disabled. [RT #35979]
- Fixed a bug that caused GeoIP ACLs not to work when referenced indirectly via named or nested ACLs. [RT #35879]
- FIxed a bug that could cause problems with cache cleaning when SIT was enabled. [RT #35858]
- Fixed a bug that caused SERVFAILs when using RPZ on a system configured as a forwarder. [RT #36060]
- Worked around a limitation in Solaris's /dev/poll implementation that could cause named to fail to start when configured to use more sockets than the system could accomodate. [RT #35878]
- Fixed a bug that could cause an assertion failure when inserting and deleting parent and child nodes in a response-policy zone. [RT #36272]
